I really love it that you guys are trying to get the Pro10 clas going again.
I started a racing series in my area -Netherlands and western part of Germany- to help the clas going again: the RC Le-Mans racing series.
We are now going for our 3rd year.
The basis of our class is just having fun in racing at insane speeds in a competitive way with a minimum of rules and low running costs.
(How many people can say thay have overtaken an 1/8th scale nitro on the the straight?
We usually have around 20 starters and growing. Till now pretty much all drivers ran 6 cell modified wide pancars.
We have seen a large variety of chassis though.
The pictures on our site speak for themselves.
The reason we can easily run 6 cell modified (and now Lipo modified) is that we run on 1/8th scale nitro outdoor tracks.
We have tested with some narrow cars, but we always came back to wide cars.
The reasons is that a wide car is simply more stable, therefore more confidence inspiring and fun to drive.
However, on small 12th scale tracks I definitely see the advantage of running narrow cars.
I tried a narrow car on some indoor carpet tracks and it was superb!
I used a Serpent Lola body with 6 3700 cells and a mildly geared and moderately timed 12 turn motor.
The car was incredibly easy to drive and ridiculously fast. I had no problem at all overtaking factory sponsored modified sedan racers!
For outdoor asphalt a wide car is in my visoin the best way to go. The cars are just easier to drive when wide.
Maybe you can include an open class (gtp bodies and wide cars) if Pro10 racing picks up again.
If you have a narrow car, it can be converted to a wide car with little effort!
Oh and if you need to choose tires, go for GRP magenta rear and purple front- all you'll ever need, both for carpet as or asphalt. Low wear, low drag and plenty of traction.
It was the tire combo of choice for 25 out of 29 drivers on the german nats 2007.
